The memory cell array includes memory blocks, and each memory block includes memory cells coupled to word-lines respectively. The word-lines are stacked vertically on a substrate, and some memory cells of the plurality of memory cells are selectable by a sub-block unit smaller than one memory block of the plurality of memory blocks. The address decoder applies an erase voltage to each of sub-blocks in a first memory block of the plurality of memory blocks through the first metal pad and the second metal pad."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Nonvolatile memory device","description":"A nonvolatile memory device includes a memory cell region having a first metal pad and a peripheral circuit region having a second metal pad and vertically connected to the memory cell region by the f","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11294580","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
